I lost about 50 pounds doing a reduced carb and calorie diet (about 50-100 carbs a day from fruits and veggies mostly, about 1500 cals) and it worked ok for a while. I switched to atkins for many reasons, but I would still recommend "reduced carb" to people who for whatever reason cannot quite swing atkins. I mean, even lower carb is better than nothing. When eating 50-100 carbs, however, calories DO count and you can't eat an atkins induction level of fats--or you'll be eating way too many cals. I'm personally a binge eater--a little bite starts off a binge--so the "all or nothing" style of early atkins (induction, OWL) suits me best when I am having a rough time. I know I will have to return to pre-maint and maint levels, but doing lowish carb proved there are some carbs I just can't eat. I cannot eat a whole piece of fruit; I cannot eat oatmeal; I cannot eat brown rice, I cannot eat whole grain cooked cereals, I cannot drink milk, diet coke, or fruit juice. Your mileage may vary. If your cravings start driving you nuts, refer to AFL (Atkins for Life) which has great suggestions for non-induction type menus. It almost sounds like you might be able to just do AFL and be no different than your hubby except in fat levels.
Another thing to consider is that it is *your* body... I regularly make meals for my sweetie that are basically protein plus vegetable/salad and I add a small serving of bread, rice, or pasta to his with no problem. I basically just make up a batch of rice and freeze it or toast a piece of garlic bread. He could care less what I eat as long as he sees good food in front of him. Maybe consider making meals that way--the base being what you eat and adding things for him? I think on south beath he'll be eating fruit (which isn't part of a meal usually anyway) and whole grains--which can easily be snuck into your basic atkins menu (Of course, you also get the good salad dressing!) Sautee and pan fry your meats using minimum amounts of oils to suit him, then add your fat in the form of cheese, avocados, and bacon on your salads and at breakfast
